ASP.Net Developer for fix simple issue

one of our connectors is to [login to view URL] for some reason, this is no-longer working. It's entirely possible that there are 2 problems, the first is that it doesn't currently work in localhost. This is easy to test. The 2nd problem is that it doesn't work in both staging and production. For this, I'll need to work with you to give you the api keys for these connections. There is a project in our product called "Meetup" with the core code for this in the file MeetupProvider.cs. The responsibility of thjs project is to connect to meetup, authenticate, and return the data for the authenticated user. The data is returned as an IEnumerable<UserActivity> which is just our internal model for storing things that people can "do" that will further their skills and their career. The problem is with Authentication I believe. So, you'll need to check out the OAuth2 flow for meetup to ensure that it works again. You can write an integration test for this. In fact, I think there already is some tests there that load stored results from a file (GetUserEvents(@"[login to view URL]")) but you might want to add a unit test that does a real Integration step that connects and authenticates with the real Meetup API for the purposes of testing this and using a temporary authentication token. But having said that, I suspect that it's the actual OAUTH flow for getting the token that's broken once again.
